How is the effect of concentration changes on the reaction rate seen in the rate law?
A. The effect of concentration changes on the rate constant affects
the reaction rate.
B. The exponents determine how much concentration changes affect
the reaction rate.
C. The rate law does not show how concentration changes would
affect the reaction rate.
D. A change in concentration of a reactant would change the
exponent of that reactant.

i believe it is-

d.) gravity pulled particles of dust and gas together to form planets.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.

answer carbon and three oxygen atoms;
